Recently, we had the opportunity to take part in a major EHR conversion project. During this “go-live,” 5 hospitals and approximately 300 ambulatory service and physician practice locations made the transition, consolidating over 100 disparate electronic systems and dozens of interfaces into one world-class medical record.

If you’ve ever been part of such an event, you know it is anything but simple. On the contrary, it requires an enormous financial investment along with years of planning, hours of meetings, and months of training. No matter how much preparation goes into it, there are sure to be bumps along the way. It is a traumatic and stressful time for all involved, but the end result is well worth the effort. Still, there are lessons to be learned and wisdom to be gleaned, and this month we’d like to share a few that we found most important. We believe that many of these are useful lessons even to those who will never live through a go-live.
 

Safety always comes first

Patient safety is a term so often used that it has a tendency to be taken for granted. Health systems build processes and procedures to ensure safety – some even win awards and recognition for their efforts. But the best (and safest) health care institutions build patient safety into their cultures. More than just being taught to use checklists or buzzwords, the staff at these institutions are encouraged to put the welfare of patients first, making all other activities secondary to this pursuit. We had the opportunity to witness the benefits of such a culture during this go-live and were incredibly impressed with the results.

To be successful in an EHR transition of any magnitude, an organization needs to hold patient safety as a core value and provide its employees with the tools to execute on that value. This enables staff to prepare adequately and to identify risks and opportunities before the conversion takes place. Once go-live occurs, staff also must feel empowered to speak up when they identify problem areas that might jeopardize patients’ care. They also must be given a clear escalation path to ensure their voices can be heard. Most importantly, everyone must understand that the electronic health record itself is just one piece of a major operational change.

As workflows are modified to adapt to the new technology, unsafe processes should be called out and fixed quickly. While the EHR may offer the latest in decision support and system integration, no advancement in technology can make up for bad outcomes, nor justify processes that lead to patient harm.
 

Training is no substitute for good support

It takes a long time to train thousands of employees, especially when that training must occur during the era of social distancing in the midst of a pandemic. Still, even in the best of times, education should be married to hands-on experience in order to have a real impact. Unfortunately, this is extremely challenging.

Trainees forget much of what they’ve learned in the weeks or months between education and go-live, so they must be given immediately accessible support to bridge the gap. This is known as “at-the-elbow” (ATE) support, and as the name implies, it consists of individuals who are familiar with the new system and are always available to end users, answering their questions and helping them navigate. Since health care never sleeps, this support needs to be offered 24/7, and it should also be flexible and plentiful.

There are many areas that will require more support than anticipated to accommodate the number of clinical and other staff who will use the system, so support staff must be nimble and available for redeployment. In addition, ensuring high-quality support is essential. As many ATE experts are hired contractors, their knowledge base and communications skills can vary widely. Accountability is key, and end users should feel empowered to identify gaps in coverage and deficits in knowledge base in the ATE.

As employees become more familiar with the new system, the need for ATE will wane, but there will still be questions that arise for many weeks to months, and new EHR users will also be added all the time. A good after–go-live support system should remain available so clinical and clerical employees can get just-in-time assistance whenever they need it.
 

Users should be given clear expectations

Clinicians going through an EHR conversion may be frustrated to discover that the data transferred from their old system into the new one is not quite what they expected. While structured elements such as allergies and immunizations may transfer, unstructured patient histories may not come over at all.

There may be gaps in data, or the opposite may even be true: an overabundance of useless information may transfer over, leaving doctors with dozens of meaningless data points to sift through and eliminate to clean up the chart. This can be extremely time-consuming and discouraging and may jeopardize the success of the go-live.

Providers deserve clear expectations prior to conversion. They should be told what will and will not transfer and be informed that there will be extra work required for documentation at the outset. They may also want the option to preemptively reduce patient volumes to accommodate the additional effort involved in preparing charts. No matter what, this will be a heavy lift, and physicians should understand the implications long before go-live to prepare accordingly.
 

Old habits die hard

One of the most common complaints we’ve heard following EHR conversions is that “things just worked better in the old system.” We always respond with a question: “Were things better, or just different?” The truth may lie somewhere in the middle, but there is no question that muscle memory develops over many years, and change is difficult no matter how much better the new system is. Still, appropriate expectations, access to just-in-time support, and a continual focus on safety will ensure that the long-term benefits of a patient-centered and integrated electronic record will far outweigh the initial challenges of go-live.

One of the top research journals in the United States has placed its editor-in-chief on administrative leave pending the outcome of an investigation into a controversial podcast episode that critics labeled as racist.

The American Medical Association’s Joint Oversight Committee announced that Howard Bauchner, MD, is on leave beginning at the end of the day on March 25. Dr. Bauchner is the top editor at JAMA, the journal of the AMA.

“The decision to place the editor-in-chief on administrative leave neither implicates nor exonerates individuals and is standard operating procedure for such investigations,” the committee said in a statement.

More than 2,000 people signed a petition on Change.org calling for an investigation at JAMA over the February podcast episode, called “Structural Racism for Doctors: What Is It?”

Already, Edward H. Livingston, MD, the host of the podcast, has resigned as deputy editor of the journal.

During the podcast, Dr. Livingston, who is White, said, “Structural racism is an unfortunate term. Personally, I think taking racism out of the conversation will help. Many of us are offended by the concept that we are racist.”

The audio of the podcast has been deleted from JAMA’s website. In its place is audio of a statement from Dr. Bauchner. In his statement, which he released in the week prior to his being on leave, he said the comments in the podcast, which also featured Mitch Katz, MD, were “inaccurate, offensive, hurtful, and inconsistent with the standards of JAMA.”

Also deleted was a JAMA tweet promoting the podcast episode. The tweet said: “No physician is racist, so how can there be structural racism in health care? An explanation of the idea by doctors for doctors in this user-friendly podcast.”

This story will be updated.

The new SARS-CoV-2 variants are not just problems for humans. 

New research shows they can also infect animals, and for the first time, variants have been able to infect mice, a development that may complicate efforts to rein in the global spread of the virus.

In addition, two new studies have implications for pets. Veterinarians in Texas and the United Kingdom have documented infections of B.1.1.7 – the fast-spreading variant first found in the United Kingdom – in dogs and cats. The animals in the U.K. study also had heart damage, but it’s unclear if the damage was caused by the virus or was already there and was found as a result of their infections.

Animal studies of SARS-CoV-2 and its emerging variants are urgent, said Sarah Hamer, DVM, PhD, a veterinarian and epidemiologist at Texas A&M University, College Station. 

She’s part of a network of scientists who are swabbing the pets of people who are diagnosed with COVID-19 to find out how often the virus passes from people to animals.

The collaboration is part of the One Health initiative through the Centers for Disease Control and Prevention. One Health aims to tackle infectious diseases by recognizing that people can’t be fully protected from pathogens unless animals and the environment are also safeguarded. “Over 70% of emerging diseases of humans have their origins in animal populations,” Dr. Hamer said. “So if we are only focusing on studying disease as it emerges in humans and ignoring where those pathogens have been transmitted or circulating for years, then we might miss the ability to detect early emergence. We might miss the ability to control these diseases before they become problems for human health.”
 

Variants move to mice

In new work, researchers at the Institut Pasteur in Paris have shown that the B.1.351 and P.1 variants of concern, which were first identified in South Africa and Brazil, respectively, can infect mice, giving the virus a potential new host. Older versions of the virus couldn’t infect mice because they weren’t able bind to receptors on their cells. These two variants can.

On one hand, that’s a good thing, because it will help scientists more easily conduct experiments in mice. Before, if they wanted to do an experiment with SARS-CoV-2 in mice, they had to use a special strain of mouse that was bred to carry human ACE2 receptors on their lung cells. Now that mice can become naturally infected, any breed will do, making it less costly and time-consuming to study the virus in animals.

On the other hand, the idea that the virus could have more and different ways to spread isn’t good news.

“From the beginning of the epidemic and since human coronaviruses emerged from animals, it has been very important to establish in which species the virus can replicate, in particular the species that live close to humans,” said Xavier Montagutelli, DVM, PhD, head of the Mouse Genetics Laboratory at the Institut Pasteur. His study was published as a preprint ahead of peer review on BioRXIV.

Once a virus establishes itself within a population of animals, it will continue to spread and change and may eventually be passed back to humans. It’s the reason that birds and pigs are closely monitored for influenza viruses.

So far, with SARS-CoV-2, only one animal has been found to catch and spread the virus and pass it back to people – farmed mink. Researchers have also documented SARS-CoV-2 antibodies in escaped mink living near mink farms in Utah, suggesting the virus has the potential to be transmitted to wild populations.

And the move of the virus into mice suggests that SARS-CoV-2 could establish itself in a population of wild animals that live close to humans.

“At this point, we have no evidence that wild mice are infected, or can become infected from humans,” Dr. Montagutelli said. He added that his findings emphasize the need to regularly test animals for signs of the infection. He said these surveys will need to be updated as more variants emerge.

“So far, we’ve been lucky that our livestock species aren’t really susceptible to this,” said Scott Weese, DVM, a professor at Ontario Veterinary College at the University of Guelph, who studies emerging infectious diseases that pass between animals and people.

While the outbreaks on mink farms have been bad, imagine what would happen, Dr. Weese said, if the virus moved to pigs.

“If this infects a barn with a few thousand pigs – which is like the mink scenario – but we have a lot more pig farms than mink farms,” he said.

“With these variants, we have to reset,” he said. “We’ve figured all this about animals and how it spreads or how it doesn’t, but now we need to repeat all those studies to make sure it’s the same thing.”
 

Pets catch variants, too

Pets living with people who are infected with SARS-CoV-2 can catch it from their owners, and cats are particularly susceptible, Dr. Weese said. 

Contact tracing studies, which also tested animals for signs of the virus, have found that about half of cats living with infected people have signs of infection, while 20%-30% of dogs were sick.

“It’s quite common,” for pets to get COVID, Dr. Weese said.

Now, two new studies have shown that pets can also be infected by the newer B.1.1.7 variant.

The first study, from researchers at Texas A&M, documented the variant in a dog and a cat from Brazos County, Texas. Neither the older black Lab mix or the older domestic shorthair cat had symptoms of COVID-19. They were tested as part of a project funded by the CDC.

Dr. Weese said pets are at risk by people who are infected, but they don’t seem to play a big role in spreading the disease to humans. So if you have pets, there’s no reason to worry that they could bring the virus home to you. You’re more likely to be a risk to them.

The second study, from a specialty animal hospital in southeast England, documented infection by the B.1.1.7 virus variant in 11 dogs and cats. Most of the pets had unusual symptoms, including inflamed hearts and heart damage.

Dr. Weese called this study interesting and said its findings deserve more investigation, but pointed out that the study can’t determine whether the infection caused the heart damage, or whether it was already there.

“This is a human virus. There’s no doubt about it. It can affect other species, but it likes people a lot better,” he said. “If you think about the big picture and what is the potential role of animals, pets are pretty low risk.”

Dr. Weese called this study interesting and said its findings deserve more investigation, but pointed out that the study can’t determine whether the infection caused the heart damage, or whether it was already there.

“This is a human virus. There’s no doubt about it. It can affect other species, but it likes people a lot better,” he said. “If you think about the big picture and what is the potential role of animals, pets are pretty low risk.”

The new SARS-CoV-2 variants are not just problems for humans. 

New research shows they can also infect animals, and for the first time, variants have been able to infect mice, a development that may complicate efforts to rein in the global spread of the virus.

In addition, two new studies have implications for pets. Veterinarians in Texas and the United Kingdom have documented infections of B.1.1.7 – the fast-spreading variant first found in the United Kingdom – in dogs and cats. The animals in the U.K. study also had heart damage, but it’s unclear if the damage was caused by the virus or was already there and was found as a result of their infections.

Animal studies of SARS-CoV-2 and its emerging variants are urgent, said Sarah Hamer, DVM, PhD, a veterinarian and epidemiologist at Texas A&M University, College Station. 

She’s part of a network of scientists who are swabbing the pets of people who are diagnosed with COVID-19 to find out how often the virus passes from people to animals.

The collaboration is part of the One Health initiative through the Centers for Disease Control and Prevention. One Health aims to tackle infectious diseases by recognizing that people can’t be fully protected from pathogens unless animals and the environment are also safeguarded. “Over 70% of emerging diseases of humans have their origins in animal populations,” Dr. Hamer said. “So if we are only focusing on studying disease as it emerges in humans and ignoring where those pathogens have been transmitted or circulating for years, then we might miss the ability to detect early emergence. We might miss the ability to control these diseases before they become problems for human health.”
 

Variants move to mice

In new work, researchers at the Institut Pasteur in Paris have shown that the B.1.351 and P.1 variants of concern, which were first identified in South Africa and Brazil, respectively, can infect mice, giving the virus a potential new host. Older versions of the virus couldn’t infect mice because they weren’t able bind to receptors on their cells. These two variants can.

On one hand, that’s a good thing, because it will help scientists more easily conduct experiments in mice. Before, if they wanted to do an experiment with SARS-CoV-2 in mice, they had to use a special strain of mouse that was bred to carry human ACE2 receptors on their lung cells. Now that mice can become naturally infected, any breed will do, making it less costly and time-consuming to study the virus in animals.

On the other hand, the idea that the virus could have more and different ways to spread isn’t good news.

“From the beginning of the epidemic and since human coronaviruses emerged from animals, it has been very important to establish in which species the virus can replicate, in particular the species that live close to humans,” said Xavier Montagutelli, DVM, PhD, head of the Mouse Genetics Laboratory at the Institut Pasteur. His study was published as a preprint ahead of peer review on BioRXIV.

Once a virus establishes itself within a population of animals, it will continue to spread and change and may eventually be passed back to humans. It’s the reason that birds and pigs are closely monitored for influenza viruses.

So far, with SARS-CoV-2, only one animal has been found to catch and spread the virus and pass it back to people – farmed mink. Researchers have also documented SARS-CoV-2 antibodies in escaped mink living near mink farms in Utah, suggesting the virus has the potential to be transmitted to wild populations.

And the move of the virus into mice suggests that SARS-CoV-2 could establish itself in a population of wild animals that live close to humans.

“At this point, we have no evidence that wild mice are infected, or can become infected from humans,” Dr. Montagutelli said. He added that his findings emphasize the need to regularly test animals for signs of the infection. He said these surveys will need to be updated as more variants emerge.

“So far, we’ve been lucky that our livestock species aren’t really susceptible to this,” said Scott Weese, DVM, a professor at Ontario Veterinary College at the University of Guelph, who studies emerging infectious diseases that pass between animals and people.

While the outbreaks on mink farms have been bad, imagine what would happen, Dr. Weese said, if the virus moved to pigs.

“If this infects a barn with a few thousand pigs – which is like the mink scenario – but we have a lot more pig farms than mink farms,” he said.

“With these variants, we have to reset,” he said. “We’ve figured all this about animals and how it spreads or how it doesn’t, but now we need to repeat all those studies to make sure it’s the same thing.”
 

Pets catch variants, too

Pets living with people who are infected with SARS-CoV-2 can catch it from their owners, and cats are particularly susceptible, Dr. Weese said. 

Contact tracing studies, which also tested animals for signs of the virus, have found that about half of cats living with infected people have signs of infection, while 20%-30% of dogs were sick.

“It’s quite common,” for pets to get COVID, Dr. Weese said.

Now, two new studies have shown that pets can also be infected by the newer B.1.1.7 variant.

The first study, from researchers at Texas A&M, documented the variant in a dog and a cat from Brazos County, Texas. Neither the older black Lab mix or the older domestic shorthair cat had symptoms of COVID-19. They were tested as part of a project funded by the CDC.

Dr. Weese said pets are at risk by people who are infected, but they don’t seem to play a big role in spreading the disease to humans. So if you have pets, there’s no reason to worry that they could bring the virus home to you. You’re more likely to be a risk to them.

Patients treated with infliximab for inflammatory bowel disease (IBD) showed significantly reduced response to COVID-19 antibodies, compared with those treated with vedolizumab, according to data from nearly 7,000 patients.

Although anti–tumor necrosis factor (anti-TNF) drugs are routinely used for patients with IBD, the impact of their immune-suppressing properties on protective immunity to COVID-19 is unknown, wrote Nicholas A. Kennedy, MD, of the University of Exeter (England) and colleagues. These drugs have been reported to impair protective immunity following vaccines for other diseases, such as those for influenza and viral hepatitis.

“By suppressing immune responses, biological and immunosuppression therapies may lead to chronic SARS-CoV-2 infection and have recently been implicated in the evolution and emergence of novel variants,” they noted, citing a study published in Cell.

In the current study, published in Gut, the researchers used data from the CLARITY IBD study to identify 6,935 patients with IBD aged 5 years and older seen at 92 hospitals in the United Kingdom between Sept. 22, 2020, and Dec. 23, 2020. Of these, 4,685 were treated with infliximab, and 2,250 received vedolizumab. The proportion of study participants with a positive anti–SARS-CoV-2 antibody test was the primary outcome, with secondary outcomes including proportion with positive antibodies following positive polymerase chain reaction test for SARS-CoV-2 and the magnitude of antibody reactivity.

Substantial seroprevalence differences seen

Overall, rates of symptomatic and proven SARS-CoV-2 infection and hospitalization were similar between infliximab-treated and vedolizumab-treated patients with IBD. However, seroprevalence was significantly lower in the infliximab group, compared with the vedolizumab group (3.4% vs. 6.0%; P < .0001). In addition, infliximab and immunomodulator use were each independently associated with lower seropositivity, compared with vedolizumab (odds ratio, 0.66 for infliximab and OR, 0.70 for immunomodulators) in a multivariate analysis.

In a sensitivity analysis, 39 of 81 infliximab-treated patients with polymerase chain reaction–confirmed COVID-19 infection seroconverted (48%), compared with 30 of 36 vedolizumab-treated patients (83%) (P < .00044). Infliximab-treated patients with confirmed infections also showed a lower magnitude of anti–SARS-CoV-2 reactivity, compared with vedolizumab-treated patients (P < .0001).

From a clinical perspective, the lower seroconversion rates and reduced levels of anti–SARS-CoV-2 antibody reactivity might increase susceptibility to recurrent COVID-19 infections in infliximab-treated IBD patients, the researchers noted. In addition, the impaired serological responses might promote chronic nasopharyngeal colonization and consequently promote the development of COVID-19 variants and drive persistent transmission, the researchers said.

The study findings were limited by several factors including lack of knowledge on the impact of attenuated immune response on infection risk, the potential for recall bias associated with patient reports, and the focus on infliximab only, the researchers pointed out. However, the key findings are likely apply to other anti-TNF monoclonal antibodies including adalimumab, certolizumab and golimumab, they suggested.

The study was strengthened by the recruitment of a large number of patients in a narrow time frame and comprehensive collection of data on patient-reported outcomes, COVID-19 testing, and serological assay results, the researchers said. Overall, the findings support the public health value of serological testing and virus surveillance to identify suboptimal vaccine response and to consider implications for practice, they added. “If attenuated serological responses following vaccination are also observed, then modified immunization strategies will need to be designed for millions of patients worldwide,” they emphasized.

Findings inform clinical practice and public health

The study is very important for many reasons, said Kim L. Isaacs, MD, PhD, AGAF, of the University of North Carolina at Chapel Hill in an interview. “It is known that there is decreased responsiveness to a number of routine vaccinations in IBD patients on immune active therapy. In terms of SARS-CoV-2, development of an immune response with infection is important in terms of severity of infection, reinfection, and possibly limiting spread of infection in this patient population,” she said. “Looking at both serum seroconversion and reactivity of immune response in patients with known SARS-CoV-2 infection will help to define clinical and public health guidance, and also may be predictive as to what might happen with SARS-CoV-2 immunization based on background biologic or immunosuppressant therapy,” she noted.

Dr. Isaacs said that she was not surprised by the study findings. “Anti-TNF, thiopurine, and methotrexate therapy are all thought to be systemically active and likely to suppress the immune response to infection and vaccination,” she said. Vedolizumab, on the other hand, is thought to be less systemically active and clinically is associated with fewer serious infections.

Data will drive patient counseling 

“These results affect counseling of IBD patients on immune active therapy who have had a SARS-CoV-2 infection,” said Dr. Isaacs. “They should be made aware that infection does not indicate protection for further infection. Although the issues that are raised in this study are of concern, patients should not have clinically beneficial therapy discontinued or switched based on these results,” she said.

“Additional research is needed to determine what the seroconversion rate is with the currently available immunizations for SARS-CoV-2,” said Dr. Isaacs. More questions to address include whether there are differences in the different products available, whether immunization after SARS-CoV-2 infection improves both seroconversion and immune reactivity, and whether there is any benefit to transiently stopping dual immune active therapy during the time of immunization, she said.

Further studies can fill knowledge gaps

“There is a knowledge gap in our understanding of susceptibility to SARS-CoV-2 infections among patients with IBD who have previously been infected,” Shirley Cohen-Mekelburg, MD, MS, staff physician and research scientist in the inflammatory bowel disease program at the Veterans Affairs Ann Arbor (Mich.) Healthcare System, said in an interview. ”This is a first step in beginning to narrow this gap – to provide patients and providers with data to drive recommendations during this COVID-19 pandemic.”

She added that, while further work needs to be done, the study findings do support potential benefit for ongoing vigilance among patients receiving infliximab for IBD. “The study findings also drive us to seek answers to more questions: For example, should we consider serological testing for patients on infliximab? How does the presence or absence of anti–SARS-CoV-2 antibodies associate with susceptibility to infection for patients with infliximab?

“Further studies examining anti–SARS-CoV-2 reactivity are necessary to better understand antibody responses between patients with IBD to the general population, or between patients on immunosuppressive therapy and the general population,” she said. “Observational studies are also not designed to examine the causal relationship between infections, medications, and antibody responses. There may be some inherent differences to patients who receive infliximab as compared to vedolizumab for IBD.”

The study was supported by Biogen (Switzerland), Celltrion Healthcare, Galapagos, F. Hoffmann-La Roche, Hull University Teaching Hospital NHS Trust, and the Royal Devon and Exeter NHS Foundation Trust. The study authors disclosed financial and nonfinancial relationships with numerous companies, including AbbVie, Biogen, Celltrion Healthcare, Galapagos, F. Hoffmann-La Roche, and Immundiagnostik, as well as Janssen, who markets infliximab, and Takeda, who markets vedolizumab. Dr. Isaacs and Dr. Cohen-Mekelburg had no relevant financial conflicts to disclose.

More sleep at night, fewer or no sleep problems, and low levels of professional burnout were associated with a lower risk of developing COVID-19 among health care workers considered to be at high risk for exposure to patients with COVID-19, new evidence reveals.

PRImageFactory/iStock/Getty Images

For each additional hour of sleep at night, for example, risk for COVID-19 dropped by 12% in a study of 2844 frontline health care workers.

Furthermore, those who reported experiencing work-related burnout every day were 2.6 times more likely to report having COVID-19, to report having COVID-19 for a longer time, and to experience COVID-19 of more severity.

“This study underscores the importance of non–hygiene-related risk factors for COVID-19 and supports a holistic approach to health – including optimal sleep and job stress reduction to protect our health care workers from this and future pandemics,” senior author Sara B. Seidelmann, MD, said in an interview.

“Our findings add to the literature that sleep duration at night, sleep problems, and burnout may be risk factors for viral illnesses like COVID-19,” wrote Dr. Seidelmann and colleagues.

This is the first study to link COVID-19 risk to sleep habits – including number of hours of sleep at night, daytime napping hours, and severe sleep problems – among health care workers across multiple countries.

The study was published online March 22 in BMJ Nutrition, Prevention, and Health.

The researchers surveyed health care professionals in specialties considered to place personnel at high risk for exposure to SARS-CoV-2: critical care, emergency care, and internal medicine.

The association between sleep and burnout risk factors and COVID-19 did not vary significantly by specialty. “We didn’t detect any significant interactions between age, sex, specialty, or country,” said Dr. Seidelmann, assistant professor of clinical medicine at Columbia University College of Physicians and Surgeons, New York, and an internist at Stamford (Conn.) Hospital.

In addition to the 12% lower risk associated with each additional hour of sleep at night, each 1 additional hour of daytime napping was linked with a 6% increased risk for COVID-19 in an adjusted analysis (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.01-1.12).

Daytime napping slightly increased risk for COVID-19 in five of the six countries included in the study: France, Germany, Italy, the United Kingdom, and the United States. In contrast, in Spain, napping had a nonsignificant protective effect.

The survey asked health care workers to recall nighttime sleep duration, sleep disorders, and burnout in the year prior to onset of the COVID-19 pandemic.
 

‘Significant, close contact’ with COVID-19?

Lead author Hyunju Kim, NP, Dr. Seidelmann, and colleagues conducted the population-based, case-control study from July 17 to Sept. 25, 2020. They identified health care workers from the SurveyHealthcareGlobus (SHG) network.

Of the respondents, 72% were men. The mean age of the participants was 48 years, and the study population was 77% White, 12% Asian, 6% mixed background, 2% Black, and 1% other. (The remainder preferred not to say).

The 568 health care workers considered to have COVID-19 were classified on the basis of self-reported symptoms. Control participants had no symptoms associated with COVID-19.

All 2,844 participants answered yes to a question about having “significant close contact” with COVID-19 patients in their workplace.

Compared to reporting no sleep problems, having three such problems – difficulty sleeping at night, poor sleep continuity, and frequent use of sleeping pills – was associated with 88% greater odds of COVID-19 (OR, 1.88; 95% CI, 1.17–3.01).

Having one sleep problem was not associated with COVID-19.
 

More burnout, greater risk

The health care workers reported the severity of any work-related burnout. “There was a significant dose-response relationship between frequency of burnout and COVID-19,” the researchers noted.

Those who reported having burnout rarely or weekly had a 1.3-1.4 greater chance of reporting COVID-19 compared to those who reported having no burnout, for example.

In addition, reporting a high level of burnout was linked to about three times the risk for having COVID-19 of longer duration and of greater severity.

What drives the association between sleep problems, burnout, and higher risk for COVID-19 and severe COVID-19 remains unknown.

“The mechanism underlying these associations isn’t clear, but suboptimal sleep, sleep disorders, and stress may result in immune system dysregulation, increased inflammation, and alterations in hormones such as cortisol and melatonin that may increase vulnerability to viral infections,” Dr. Seidelmann said.

Using a large network of health care workers in the early phase of the pandemic is a strength of the study. How generalizable the findings are outside the SHG database of 1.5 million health care workers remains unknown.

Another limitation was reliance on self-reporting of COVID-19 patient exposure, outcomes, and covariates, which could have introduced bias.

“However,” the researchers noted, “health care workers are likely a reliable source of information.”
 

Insomnia a common challenge

A 2020 meta-analysis examined the effect of insomnia and psychological factors on COVID-19 risk among health care workers. Lead author Kavita Batra, PhD, of the University of Nevada, Las Vegas (UNLV), and colleagues found that the pooled prevalence of insomnia was almost 28%.

“The recent six-country study by Kim and colleagues also underscores this relationship between lack of sleep and having higher odds of COVID-19 infection,” Manoj Sharma, MBBS, PhD, professor of social and behavioral health in the UNLV department of environmental and occupational health, and one of the study authors, said in an interview.

More research is warranted to learn the direction of the association, he said. Does reduced sleep lower immunity and make a health care worker more susceptible to SARS-CoV-2 infection, or does the anxiety associated with COVID-19 contribute to insomnia?

“Practicing sleep hygiene is a must not only for health workers but also for everyone,” Dr. Sharma added. Recommendations include having fixed hours of going to bed, fixed hours of waking up, not overdoing naps, having at least 30 minutes of winding down before sleeping, having a dark bedroom devoid of all electronics and other disturbances, avoiding smoking, alcohol, and stimulants (such as caffeine) before sleeping, and practicing relaxation right before sleeping, he said.

“It is hard for some health care workers, especially those who work night shifts, but it must be a priority to follow as many sleep hygiene measures as possible,” Dr. Sharma said. “After all, if you do not take care of yourself how can you take care of others?”

Dr. Seidelmann, Dr. Batra, and Dr. Sharma have disclosed no relevant financial relationships.

More sleep at night, fewer or no sleep problems, and low levels of professional burnout were associated with a lower risk of developing COVID-19 among health care workers considered to be at high risk for exposure to patients with COVID-19, new evidence reveals.

For each additional hour of sleep at night, for example, risk for COVID-19 dropped by 12% in a study of 2844 frontline health care workers.

Furthermore, those who reported experiencing work-related burnout every day were 2.6 times more likely to report having COVID-19, to report having COVID-19 for a longer time, and to experience COVID-19 of more severity.

“This study underscores the importance of non–hygiene-related risk factors for COVID-19 and supports a holistic approach to health – including optimal sleep and job stress reduction to protect our health care workers from this and future pandemics,” senior author Sara B. Seidelmann, MD, said in an interview.

“Our findings add to the literature that sleep duration at night, sleep problems, and burnout may be risk factors for viral illnesses like COVID-19,” wrote Dr. Seidelmann and colleagues.

This is the first study to link COVID-19 risk to sleep habits – including number of hours of sleep at night, daytime napping hours, and severe sleep problems – among health care workers across multiple countries.

The study was published online March 22 in BMJ Nutrition, Prevention, and Health.

The researchers surveyed health care professionals in specialties considered to place personnel at high risk for exposure to SARS-CoV-2: critical care, emergency care, and internal medicine.

The association between sleep and burnout risk factors and COVID-19 did not vary significantly by specialty. “We didn’t detect any significant interactions between age, sex, specialty, or country,” said Dr. Seidelmann, assistant professor of clinical medicine at Columbia University College of Physicians and Surgeons, New York, and an internist at Stamford (Conn.) Hospital.

In addition to the 12% lower risk associated with each additional hour of sleep at night, each 1 additional hour of daytime napping was linked with a 6% increased risk for COVID-19 in an adjusted analysis (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.01-1.12).

Daytime napping slightly increased risk for COVID-19 in five of the six countries included in the study: France, Germany, Italy, the United Kingdom, and the United States. In contrast, in Spain, napping had a nonsignificant protective effect.

The survey asked health care workers to recall nighttime sleep duration, sleep disorders, and burnout in the year prior to onset of the COVID-19 pandemic.
 

‘Significant, close contact’ with COVID-19?

Lead author Hyunju Kim, NP, Dr. Seidelmann, and colleagues conducted the population-based, case-control study from July 17 to Sept. 25, 2020. They identified health care workers from the SurveyHealthcareGlobus (SHG) network.

Of the respondents, 72% were men. The mean age of the participants was 48 years, and the study population was 77% White, 12% Asian, 6% mixed background, 2% Black, and 1% other. (The remainder preferred not to say).

The 568 health care workers considered to have COVID-19 were classified on the basis of self-reported symptoms. Control participants had no symptoms associated with COVID-19.

All 2,844 participants answered yes to a question about having “significant close contact” with COVID-19 patients in their workplace.

Compared to reporting no sleep problems, having three such problems – difficulty sleeping at night, poor sleep continuity, and frequent use of sleeping pills – was associated with 88% greater odds of COVID-19 (OR, 1.88; 95% CI, 1.17–3.01).

Having one sleep problem was not associated with COVID-19.
 

More burnout, greater risk

The health care workers reported the severity of any work-related burnout. “There was a significant dose-response relationship between frequency of burnout and COVID-19,” the researchers noted.

Those who reported having burnout rarely or weekly had a 1.3-1.4 greater chance of reporting COVID-19 compared to those who reported having no burnout, for example.

In addition, reporting a high level of burnout was linked to about three times the risk for having COVID-19 of longer duration and of greater severity.

What drives the association between sleep problems, burnout, and higher risk for COVID-19 and severe COVID-19 remains unknown.

“The mechanism underlying these associations isn’t clear, but suboptimal sleep, sleep disorders, and stress may result in immune system dysregulation, increased inflammation, and alterations in hormones such as cortisol and melatonin that may increase vulnerability to viral infections,” Dr. Seidelmann said.

After declining for 8 consecutive weeks, new cases of COVID-19 rose among children in the United States, according to the American Academy of Pediatrics and the Children’s Hospital Association.

A total of 57,078 new cases were reported in children during the week of March 12-18, compared with 52,695 for the previous week, ending a streak of declines going back to mid-January, the AAP and CHA said in their weekly COVID-19 report.

Also up for the week was the proportion of all cases occurring in children. The 57,000-plus cases represented 18.7% of the total (304,610) for all ages, and that is the largest share of the new-case burden for the entire pandemic. The previous high, 18.0%, came just 2 weeks earlier, based on data collected from 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

Speaking of the entire pandemic, the total number of COVID-19 cases in children is over 3.34 million, and that represents 13.3% of cases among all ages in the United States. The cumulative rate of infection as of March 18 was 4,440 cases per 100,000 children, up from 4,364 per 100,000 a week earlier, the AAP and CHA said.

At the state level, Vermont has now passed the 20% mark (20.1%, to be exact) for children’s proportion of cases and is higher in that measure than any other state. The highest rate of infection (8,763 cases per 100,000) can be found in North Dakota, the AAP/CHA data show.

There were only two new coronavirus-related deaths during the week of March 12-18 after Kansas revised its mortality data, bringing the total to 268 in the 46 jurisdictions (43 states, New York City, Puerto Rico, and Guam) that are reporting deaths by age, the AAP and CHA said.

Women with polycystic ovary syndrome (PCOS) face an almost 30% increased risk for COVID-19 compared with unaffected women, even after adjusting for cardiometabolic and other related factors, suggests an analysis of United Kingdom primary care data.

“Our research has highlighted that women with PCOS are an often overlooked and potentially high-risk population for contracting COVID-19,” said joint senior author Wiebke Arlt, MD, PhD, director of the Institute of Metabolism and Systems Research at the University of Birmingham (England), in a press release.

“Before the onset of the COVID-19 pandemic, women with PCOS consistently report fragmented care, delayed diagnosis and a perception of poor clinician understanding of their condition,” added co-author Michael W. O’Reilly, MD, PhD, University of Medicine and Health Sciences, Dublin.

“Women suffering from this condition may fear, with some degree of justification, that an enhanced risk of COVID-19 infection will further compromise timely access to health care and serve to increase the sense of disenfranchisement currently experienced by many patients,” he added.

Consequently, “these findings need to be considered when designing public health policy and advice as our understanding of COVID-19 evolves,” noted first author Anuradhaa Subramanian, PhD Student, Institute of Applied Health Research, University of Birmingham.

The research was published by the European Journal of Endocrinology on March 9.
 

Women with PCOS: A distinct subgroup?

PCOS, which is thought to affect up to 16% of women, is associated with a significantly increased risk for type 2 diabetes, non-alcoholic fatty liver disease, and cardiovascular disease, all which have been linked to more severe COVID-19.

The condition is more prevalent in Black and South Asian women, who also appear to have an increased risk for severe COVID-19 vs. their White counterparts.

However, women and younger people in general have a lower overall risk for severe COVID-19 and mortality compared with older people and men.

Women with PCOS may therefore “represent a distinct subgroup of women at higher than average [on the basis of their sex and age] risk of adverse COVID-19–related outcomes,” the researchers note.

To investigate further, they collated data from The Health Improvement Network primary care database, which includes information from 365 active general practices in the U.K. for the period Jan. 31, 2020, to July 22, 2020.

They identified women with PCOS or a coded diagnosis of polycystic ovaries (PCO), and then for each woman randomly selected four unaffected controls matched for age and general practice location.

They included 21,292 women with PCOS/PCO and 78,310 controls, who had a mean age at study entry of 39.3 years and 39.5 years, respectively. The mean age at diagnosis of PCOS was 27 years, and the mean duration of the condition was 12.4 years.

The crude incidence of COVID-19 was 18.1 per 1000 person-years among women with PCOS vs. 11.9 per 1000 person-years in those without.

Cox regression analysis adjusted for age indicated that women with PCOS faced a significantly increased risk for COVID-19 than those without, at a hazard ratio of 1.51 (P < .001).

Further adjustment for body mass index (BMI) and age reduced the hazard ratio to 1.36 (P = .001).

In the fully adjusted model, which also took into account impaired glucose regulation, androgen excess, anovulation, hypertension, and other PCOS-related factors, the hazard ratio remained significant, at 1.28 (P = .015).
 

For shielding, balance benefits with impact on mental health

Joint senior author Krishnarajah Nirantharakumar, MD, PhD, also of the University of Birmingham, commented that, despite the increased risks, shielding strategies for COVID-19 need to take into account the impact of PCOS on women’s mental health.

“The risk of mental health problems, including low self-esteem, anxiety, and depression, is significantly higher in women with PCOS,” he said, “and advice on strict adherence to social distancing needs to be tempered by the associated risk of exacerbating these underlying problems.”

Arlt also pointed out that the study only looked at the incidence of COVID-19 infection, rather than outcomes.

“Our study does not provide information on the risk of a severe course of the COVID-19 infection or on the risk of COVID-19–related long-term complications [in women with PCOS], and further research is required,” she concluded.

The study was funded by Health Data Research UK and supported by the Wellcome Trust, the Health Research Board, and the National Institute for Health Research Birmingham Biomedical Research Centre based at the University of Birmingham and University Hospitals Birmingham NHS Foundation Trust. The study authors have disclosed no relevant financial relationships.

They included 21,292 women with PCOS/PCO and 78,310 controls, who had a mean age at study entry of 39.3 years and 39.5 years, respectively. The mean age at diagnosis of PCOS was 27 years, and the mean duration of the condition was 12.4 years.

The crude incidence of COVID-19 was 18.1 per 1000 person-years among women with PCOS vs. 11.9 per 1000 person-years in those without.

Cox regression analysis adjusted for age indicated that women with PCOS faced a significantly increased risk for COVID-19 than those without, at a hazard ratio of 1.51 (P < .001).

Further adjustment for body mass index (BMI) and age reduced the hazard ratio to 1.36 (P = .001).

In the fully adjusted model, which also took into account impaired glucose regulation, androgen excess, anovulation, hypertension, and other PCOS-related factors, the hazard ratio remained significant, at 1.28 (P = .015).
 

For shielding, balance benefits with impact on mental health

Joint senior author Krishnarajah Nirantharakumar, MD, PhD, also of the University of Birmingham, commented that, despite the increased risks, shielding strategies for COVID-19 need to take into account the impact of PCOS on women’s mental health.

“The risk of mental health problems, including low self-esteem, anxiety, and depression, is significantly higher in women with PCOS,” he said, “and advice on strict adherence to social distancing needs to be tempered by the associated risk of exacerbating these underlying problems.”

Arlt also pointed out that the study only looked at the incidence of COVID-19 infection, rather than outcomes.

“Our study does not provide information on the risk of a severe course of the COVID-19 infection or on the risk of COVID-19–related long-term complications [in women with PCOS], and further research is required,” she concluded.

The study was funded by Health Data Research UK and supported by the Wellcome Trust, the Health Research Board, and the National Institute for Health Research Birmingham Biomedical Research Centre based at the University of Birmingham and University Hospitals Birmingham NHS Foundation Trust. The study authors have disclosed no relevant financial relationships.

Federal regulators on March 23 said they were “concerned” that drug maker AstraZeneca included “outdated information” in its announcement the previous day that the company’s COVID-19 vaccine was effective.

The federal Data and Safety Monitoring Board shared those concerns with the company as well as with the National Institute of Allergy and Infectious Diseases, and the U.S. Biomedical Advanced Research and Development Authority, according to a statement from NIAID issued early March 23.

“We urge the company to work with the DSMB to review the efficacy data and ensure the most accurate, up-to-date efficacy data be made public as quickly as possible,” the agency said.

The NIAID statement does not say what data may have been outdated or how it may have changed the results. The company said March 22 it plans to see U.S. authorization for the vaccine in April.

The statement from NIAID comes a day after AstraZeneca said the interim results of their phase III U.S. study found it was 79% effective against symptomatic COVID-19, 80% effective in people 65 years and older, and 100% effective against severe or critical disease and hospitalization.

Company officials and clinical trial investigators on March 22 also addressed the recent concerns about blood clots, how well the vaccine will perform against variants, and provided a timeline for seeking regulatory approval.

“There are many countries in Europe and throughout the world that have already authorized this. The fact that a United States-run study has confirmed the efficacy and safety of this vaccine, I think is an important contribution to global health in general,” Anthony Fauci, MD, chief medical advisor to President Joe Biden, said during a White House press briefing March 22.

Andy Slavitt, White House senior advisor for the COVID-19 Response Team, had a more tempered reaction.

“It’s important to remind everyone we cannot and will not get ahead of the FDA,” he said. “While we would certainly call today’s news encouraging, it’s the kind of thing we like to see, we have a rigorous process that will come once an EUA is submitted and that will give us more information.”

With 30 million doses at the ready, the company plans to file for FDA emergency use authorization “within weeks,” Menelas Pangalos, executive vice president of biopharmaceuticals research and development at AstraZeneca, said during a media briefing March 22.
 

Risk of thrombosis addressed

Regarding highly publicized reports of problems with blood clots from the AstraZeneca vaccine, the World Health Organization found the vaccine creates no greater risks, as did the European Medicines Agency

“We’ve had absolute confidence in the efficacy of the vaccine. Seeing this data now I hope gives others increased confidence that this is a very safe and effective vaccine,” Mr. Pangalos said.

“We’re glad this is being investigated really thoroughly,” Magda Sobieszczyk, MD, an infectious disease specialist at Columbia University In New York City, said. “It’s incredibly reassuring that the regulatory agencies have looked at the data thoroughly and there is no enhanced signal above what is seen in the population.”

“There were no concerning signals noted in the U.S. data,” she added.

Regarding the risk of blood clots, “These data are therefore timely in further addressing any safety concerns that could undermine vaccine uptake.” Andrew Garrett, PhD, executive vice president of scientific operations at ICON Clinical Research, agreed.

The vaccine was well-tolerated, the company reported, with no serious adverse events. Temporary pain and tenderness at the injection site, mild-to-moderate headaches, fatigue, chills, fever, muscle aches. and malaise were among the reported reactions.

The phase III interim results show 141 cases of symptomatic COVID-19 in the study of 32,449 adults. “We don’t have the whole breakdown yet . . . these are the high-level results we just got this week,” Mr. Pangalos said. Further information on rates of mild to moderate COVID-19 illness between groups is not yet available, for example.

The company explained that participants were randomly assigned to vaccine or placebo, with twice as many receiving the actual vaccine.

The trial is ongoing, so the FDA will receive information on more than the 141 COVID-19 symptomatic cases when the company submits a full primary analysis to the agency, Mr. Pangalos said.

In the phase III study, patients received two doses 4 weeks apart.

Beyond the U.S. study, the company has additional information, including real-world data from the United Kingdom, that it intends to submit to the FDA. Part of this evidence suggests increased efficacy when a second dose is administered at 3 months
 

‘Robust’ findings

“This is a large study, so these results can be expected to be robust. They could be expected to be even more so if there were more cases to compare between the groups, but 141 is still a substantial number of cases,” said Peter English, MD, of Horsham, United Kingdom, who is immediate past chair of the British Medical Association Public Health Medicine Committee.

Experts welcomed the 80% efficacy in people 65 and older in particular. “Importantly, the trial provides further support for efficacy in the elderly where previous clinical trial data, other than immunologic data, had been lacking,” Dr. Garrett said.

“It is clear this vaccine has very good efficacy. Remember that 60% was, prior to any trials being started, regarded as a good target,” said Stephen Evans, professor of pharmacoepidemiology at the London School of Hygiene & Tropical Medicine. “This efficacy does not show a notable decline at older ages. This was expected and the speculation that it was ineffective or quasi-ineffective at older ages was totally unjustified.

“This is good news for the global community and one hopes that any political statements around this good news are avoided,” he added.
 

Efficacy against variants?

Regarding virus variants, Mr. Pangalos noted the study was conducted when several variants of concern were in circulation.

“What I can say is given this study was conducted much later in terms of timing, it’s very encouraging that we’ve got such high efficacy numbers when undoubtedly there are variants of concern in circulation in this study,” Mr. Pangalos said.

“It also highlights why we believe that against severe disease, our vaccine will be effective against all variants of concern,” he added.

Once the company submits its EUA to the FDA, the company is ready to immediately distribute 30 million doses of the vaccine and expects to ship 50 million total within the first month, Ruud Dobber, PhD, AstraZeneca executive vice president and president of the AZ Biopharmaceuticals Business Unit, said during the briefing.

The vaccine can be stored at 2 to 8 degrees Celsius for at least 6 months. Like other COVID-19 vaccines already authorized for emergency use, the duration of protection with the AstraZeneca product remains unknown.

Family physician Mitchell A. Kaminski, MD, MBA, was still awash in feelings of joy and relief at recently being vaccinated against COVID-19 when a patient’s comments stopped him cold. The patient, a middle-aged man with several comorbidities had just declined the pneumonia vaccine – and he added, without prompting, that he wouldn’t be getting the COVID vaccine either. This patient had heard getting vaccinated could kill him.

Dr. Kaminski countered with medical facts, including that the very rare side effects hadn’t killed anyone in the United States but COVID was killing thousands of people every day. “Well then, I’ll just risk getting COVID,” Dr. Kaminski recalled the patient saying. Conversation over.

That experience caused Dr. Kaminski, who is program director for population health at Thomas Jefferson University, Philadelphia, to rethink the way he talks to patients who are uncertain or skeptical about getting a COVID-19 vaccine. Now, if he saw that patient who seemed fearful of dying from a vaccination, Dr. Kaminski said he would be more curious.

Instead of outright contradicting the beliefs of a patient who is reluctant to get vaccinated, Dr. Kaminski now gently asks about the reasons for their discomfort and offers information about the vaccines. But mostly, he listens.

Conversations between physicians and patients about the risks that come with getting a COVID-19 vaccine are becoming more common in general as eligibility for immunizations expands. Physicians are using a variety of methods to communicate about the safety and importance of getting vaccinated that they think will lead to more of their patients getting a COVID-19 vaccine.

About 80% of Americans say that they are most likely to turn to doctors, nurses and other health professionals for help in deciding whether to get the COVID vaccine, according to research by the Kaiser Family Foundation.
 

Getting beyond the distrust

While patients often feel a strong connection with their health providers, distrust in the medical establishment still exists, especially among some populations. The Kaiser Family Foundation reported that a third of Black respondents are taking a “wait-and-see” approach, while 23% said they will get it only if it’s required – or not at all.

Distrust persists from historical racist events in medicine, such as the infamous Tuskegee experiments in which treatment was withheld from Black men with syphilis. But physicians shouldn’t assume that all Black patients have the same reasons for vaccine hesitancy, said Krys Foster, MD, MPH, a family physician at Thomas Jefferson University.

“In my experience caring for patients who are uncertain or have concerns about receiving the vaccine, I’ve learned that many are just seeking more information, or even my approval to say that it is safe to proceed given their medical history,” she said.

Sources such as the COVID Racial Data Tracker have found that Black Americans have a higher COVID death rate than other racial or ethnic groups, making vaccination even more vital. Yet fear of the vaccine could be triggered by misinformation that can be found in various places online, Dr. Foster said.

To encourage people to get vaccinated and dispel false information, Dr. Foster takes time to discuss how safe it is to get a COVID-19 vaccine and the vaccines’ side effects, then quickly pivots to discussing how to get vaccinated.

It can be difficult for some people to find appointments or access testing sites. The failure to get the vaccine shouldn’t automatically be attributed to “hesitancy,” she said. “The onus is on the medical community to help fix the health injustices inflicted on communities of color by providing equitable information and access and stop placing blame on them for having the ‘wrong’ vaccine attitude.”
 

Give your testimonial

Jamie Loehr, MD, of Cayuga Family Medicine in Ithaca, N.Y., said he has always had a higher-than-average number of patients who refused or delayed their children’s vaccines. He does not kick them out of his practice but politely continues to educate them about the vaccines.

When patients ask Dr. Loehr if he trusts the vaccine, he responds with confidence: “I not only believe in it, I got it and I recommend it to anyone who can possibly get it.”

He was surprised recently when a mother who has expressed reluctance to vaccinate her young children came for a checkup and told him she had already received a COVID vaccine. “She made the decision on her own that this was important enough that she wanted to get it,” he said.
 

Health care worker hesitancy

Some health care workers’ unease about being at the front of the line for vaccines may be another source of vaccine hesitancy among members of the general population that physicians need to address. In a survey of almost 3,500 health care workers conducted in October and November 2020 and published in January 2021 in Vaccines, only about a third (36%) said they would get the vaccine as soon as it became available. By mid- to late-February, 54% of health care workers reported having been vaccinated and another 10% planned to get the vaccine as soon as possible, according to the Kaiser Family Foundation COVID-19 Vaccine Monitor.

Resolving doubts about the vaccines requires a thoughtful approach toward health care colleagues, said Eileen Barrett, MD, MPH, an internist and hospitalist who was a coauthor of the Vaccines paper and who serves on the editorial advisory board of Internal Medicine News. “We should meet people where they are and do our best to hear their concerns, listening thoughtfully without condescension. Validate how important their role is in endorsing vaccination and also validate asking questions.”

There’s power in the strong personal testimonial of physicians and other health care workers – not just to influence patients, but as a model for fellow health professionals, as well, noted Dr. Barrett, who cares for COVID-19 patients and is associate professor in the division of hospital medicine, department of internal medicine, at the University of New Mexico, Albuquerque.
 

‘Do it for your loved ones’

The Reagan-Udall Foundation, a nonprofit organization created by Congress to support the Food and Drug Administration, tested some messaging with focus groups. Participants responded favorably to this statement about why the vaccines were developed so quickly: “Vaccine development moved faster than normal because everyone’s making it their highest priority.”

People did not feel motivated to get the vaccine out of a sense of civic duty, said Susan Winckler, RPh, Esq, who is CEO of the foundation. But they did think the following was a good reason to get vaccinated: “By getting a vaccine, I could protect my children, my parents, and other loved ones.”

Physicians also can work with community influencers, such as faith leaders, to build confidence in vaccines. That’s part of the strategy of Roll Up Your Sleeves, a campaign spearheaded by agilon health, a company that partners with physician practices to develop value-based care for Medicare Advantage patients.

For example, Wilmington Health in North Carolina answered questions about the vaccines in Facebook Live events and created a Spanish-language video to boost vaccine confidence in the Latinx community. Additionally, PriMED Physicians in Dayton, Ohio, reached out to Black churches to provide a vaccine-awareness video and a PriMED doctor participated in a webinar sponsored by the Nigerian Women Cultural Organization to help dispel myths about COVID-19 and the vaccines.

“This is a way to deepen our relationship with our patients,” said Ben Kornitzer, MD, chief medical officer of agilon. “It’s helping to walk them through this door where on one side is the pandemic and social isolation and on the other side is a return to their life and loved ones.”

The messages provided by primary care physicians can be powerful and affirming, said Ms. Winckler.

“The path forward is to make a space for people to ask questions,” she continued, noting that the Reagan-Udall Foundation provides charts that show how the timeline for vaccine development was compressed without skipping any steps.

Strategies and background information on how to reinforce confidence in COVID-19 vaccines are also available on a page of the Centers for Disease Control and Prevention’s website.

None of the experts interviewed reported any relevant conflicts of interest. The Reagan-Udall Foundation has received sponsorships from Johnson & Johnson and AstraZeneca and has had a safety surveillance contract with Pfizer.

Resolving doubts about the vaccines requires a thoughtful approach toward health care colleagues, said Eileen Barrett, MD, MPH, an internist and hospitalist who was a coauthor of the Vaccines paper and who serves on the editorial advisory board of Internal Medicine News. “We should meet people where they are and do our best to hear their concerns, listening thoughtfully without condescension. Validate how important their role is in endorsing vaccination and also validate asking questions.”

There’s power in the strong personal testimonial of physicians and other health care workers – not just to influence patients, but as a model for fellow health professionals, as well, noted Dr. Barrett, who cares for COVID-19 patients and is associate professor in the division of hospital medicine, department of internal medicine, at the University of New Mexico, Albuquerque.
 

‘Do it for your loved ones’

The Reagan-Udall Foundation, a nonprofit organization created by Congress to support the Food and Drug Administration, tested some messaging with focus groups. Participants responded favorably to this statement about why the vaccines were developed so quickly: “Vaccine development moved faster than normal because everyone’s making it their highest priority.”

People did not feel motivated to get the vaccine out of a sense of civic duty, said Susan Winckler, RPh, Esq, who is CEO of the foundation. But they did think the following was a good reason to get vaccinated: “By getting a vaccine, I could protect my children, my parents, and other loved ones.”

Physicians also can work with community influencers, such as faith leaders, to build confidence in vaccines. That’s part of the strategy of Roll Up Your Sleeves, a campaign spearheaded by agilon health, a company that partners with physician practices to develop value-based care for Medicare Advantage patients.

For example, Wilmington Health in North Carolina answered questions about the vaccines in Facebook Live events and created a Spanish-language video to boost vaccine confidence in the Latinx community. Additionally, PriMED Physicians in Dayton, Ohio, reached out to Black churches to provide a vaccine-awareness video and a PriMED doctor participated in a webinar sponsored by the Nigerian Women Cultural Organization to help dispel myths about COVID-19 and the vaccines.

“This is a way to deepen our relationship with our patients,” said Ben Kornitzer, MD, chief medical officer of agilon. “It’s helping to walk them through this door where on one side is the pandemic and social isolation and on the other side is a return to their life and loved ones.”

The messages provided by primary care physicians can be powerful and affirming, said Ms. Winckler.

“The path forward is to make a space for people to ask questions,” she continued, noting that the Reagan-Udall Foundation provides charts that show how the timeline for vaccine development was compressed without skipping any steps.

Strategies and background information on how to reinforce confidence in COVID-19 vaccines are also available on a page of the Centers for Disease Control and Prevention’s website.

None of the experts interviewed reported any relevant conflicts of interest. The Reagan-Udall Foundation has received sponsorships from Johnson & Johnson and AstraZeneca and has had a safety surveillance contract with Pfizer.

Family physician Mitchell A. Kaminski, MD, MBA, was still awash in feelings of joy and relief at recently being vaccinated against COVID-19 when a patient’s comments stopped him cold. The patient, a middle-aged man with several comorbidities had just declined the pneumonia vaccine – and he added, without prompting, that he wouldn’t be getting the COVID vaccine either. This patient had heard getting vaccinated could kill him.

Dr. Kaminski countered with medical facts, including that the very rare side effects hadn’t killed anyone in the United States but COVID was killing thousands of people every day. “Well then, I’ll just risk getting COVID,” Dr. Kaminski recalled the patient saying. Conversation over.

That experience caused Dr. Kaminski, who is program director for population health at Thomas Jefferson University, Philadelphia, to rethink the way he talks to patients who are uncertain or skeptical about getting a COVID-19 vaccine. Now, if he saw that patient who seemed fearful of dying from a vaccination, Dr. Kaminski said he would be more curious.

Instead of outright contradicting the beliefs of a patient who is reluctant to get vaccinated, Dr. Kaminski now gently asks about the reasons for their discomfort and offers information about the vaccines. But mostly, he listens.

Conversations between physicians and patients about the risks that come with getting a COVID-19 vaccine are becoming more common in general as eligibility for immunizations expands. Physicians are using a variety of methods to communicate about the safety and importance of getting vaccinated that they think will lead to more of their patients getting a COVID-19 vaccine.

About 80% of Americans say that they are most likely to turn to doctors, nurses and other health professionals for help in deciding whether to get the COVID vaccine, according to research by the Kaiser Family Foundation.
 

Getting beyond the distrust

While patients often feel a strong connection with their health providers, distrust in the medical establishment still exists, especially among some populations. The Kaiser Family Foundation reported that a third of Black respondents are taking a “wait-and-see” approach, while 23% said they will get it only if it’s required – or not at all.

Distrust persists from historical racist events in medicine, such as the infamous Tuskegee experiments in which treatment was withheld from Black men with syphilis. But physicians shouldn’t assume that all Black patients have the same reasons for vaccine hesitancy, said Krys Foster, MD, MPH, a family physician at Thomas Jefferson University.

“In my experience caring for patients who are uncertain or have concerns about receiving the vaccine, I’ve learned that many are just seeking more information, or even my approval to say that it is safe to proceed given their medical history,” she said.

Sources such as the COVID Racial Data Tracker have found that Black Americans have a higher COVID death rate than other racial or ethnic groups, making vaccination even more vital. Yet fear of the vaccine could be triggered by misinformation that can be found in various places online, Dr. Foster said.

To encourage people to get vaccinated and dispel false information, Dr. Foster takes time to discuss how safe it is to get a COVID-19 vaccine and the vaccines’ side effects, then quickly pivots to discussing how to get vaccinated.

It can be difficult for some people to find appointments or access testing sites. The failure to get the vaccine shouldn’t automatically be attributed to “hesitancy,” she said. “The onus is on the medical community to help fix the health injustices inflicted on communities of color by providing equitable information and access and stop placing blame on them for having the ‘wrong’ vaccine attitude.”
 

Give your testimonial

Jamie Loehr, MD, of Cayuga Family Medicine in Ithaca, N.Y., said he has always had a higher-than-average number of patients who refused or delayed their children’s vaccines. He does not kick them out of his practice but politely continues to educate them about the vaccines.

When patients ask Dr. Loehr if he trusts the vaccine, he responds with confidence: “I not only believe in it, I got it and I recommend it to anyone who can possibly get it.”

He was surprised recently when a mother who has expressed reluctance to vaccinate her young children came for a checkup and told him she had already received a COVID vaccine. “She made the decision on her own that this was important enough that she wanted to get it,” he said.
 

Health care worker hesitancy

Some health care workers’ unease about being at the front of the line for vaccines may be another source of vaccine hesitancy among members of the general population that physicians need to address. In a survey of almost 3,500 health care workers conducted in October and November 2020 and published in January 2021 in Vaccines, only about a third (36%) said they would get the vaccine as soon as it became available. By mid- to late-February, 54% of health care workers reported having been vaccinated and another 10% planned to get the vaccine as soon as possible, according to the Kaiser Family Foundation COVID-19 Vaccine Monitor.

None of the experts interviewed reported any relevant conflicts of interest. The Reagan-Udall Foundation has received sponsorships from Johnson & Johnson and AstraZeneca and has had a safety surveillance contract with Pfizer.

Pregnant women can safely get vaccinated with the Pfizer-BioNTech and Moderna vaccines for COVID-19, surveillance data from the Centers for Disease Control and Prevention suggest.

More than 30,000 women who received these vaccines have reported pregnancies through the CDC’s V-Safe voluntary reporting system, and their rates of complications are not significantly different from those of unvaccinated pregnant women, said Tom Shimabukuro, MD, MPH, MBA, deputy director of the CDC Immunization Safety Office.

“Overall, the data are reassuring with respect to vaccine safety in pregnant women,” he told this news organization.

Dr. Shimabukuro presented the data during a March 1 meeting of the Advisory Committee on Immunization Practices, a group of health experts selected by the Secretary of the U.S. Department of Health & Human Services.

The CDC has included pregnancy along with other underlying conditions that qualify people to be offered vaccines in the third priority tier (Phase 1c).

“There is evidence that pregnant women who get COVID-19 are at increased risk of severe illness and complications from severe illness,” Dr. Shimabukuro explained. “And there is also evidence that pregnant persons who get COVID-19 may be at increased risk for adverse pregnancy outcomes.”

The American College of Obstetrics and Gynecology recommends that “COVID-19 vaccines should not be withheld from pregnant individuals.”

By contrast, the World Health Organization recommends the vaccines only for those pregnant women who are “at high risk of exposure to SARS-CoV-2 (for example, health workers) or who have comorbidities which add to their risk of severe disease.”

Not enough information was available from the pivotal trials of the Moderna and Pfizer vaccines to assess risk in pregnant women, according to these manufacturers. Pfizer has announced a follow-up trial of its vaccine in healthy pregnant women.

Analyzing surveillance data

To better assess whether the Pfizer or Moderna vaccines cause problems in pregnancy or childbirth, Dr. Shimabukuro and colleagues analyzed data from V-Safe and the Vaccine Adverse Event Reporting System (VAERS).

The CDC encourages providers to inform people they vaccinate about the V-Safe program. Participants can voluntarily enter their data through a website, and may receive follow-up text messages and phone calls from the CDC asking for additional information at various times after vaccination. It is not a systematic survey, and the sample is not necessarily representative of everyone who gets the vaccine, Dr. Shimabukuro noted.

At the time of the study, V-Safe recorded 55,220,364 reports from people who received at least one dose of the Pfizer or Moderna vaccine through Feb. 16. These included 30,494 pregnancies, of which 16,039 were in women who received the Pfizer vaccine and 14,455 in women who received the Moderna vaccine.

Analyzing data collected through Jan. 13, 2021, the researchers found that both local and systemic reactions were similar between pregnant and nonpregnant women aged 16-54 years.

Most women reported pain, and some reported swelling, redness, and itching at the injection site. Of systemic reactions, fatigue was the most common, followed by headache, myalgia, chills, nausea, and fever. The systemic reactions were more common with the second Pfizer dose; fatigue affected a majority of both pregnant and nonpregnant women. Data on the second Moderna dose were not available.

The CDC enrolled 1,815 pregnant women for additional follow-up, among whom there were 275 completed pregnancies and 232 live births.

Rates of outcomes “of interest” were no higher among these women than in the general population. 

In contrast to V-Safe, data from VAERS, comanaged by the CDC and U.S. Food and Drug Administration, are from spontaneous reports of adverse events. The sources for those reports are varied. “That could be the health care provider,” Dr. Shimabukuro said. “That could be the patient themselves. It could be a caregiver for children.”  

Just 154 VAERS reports through Feb. 16 concerned pregnant women, and of these, only 42 (27%) were for pregnancy-specific conditions, with the other 73% representing the types of adverse events reported for the general population of vaccinated people, such as headache and fatigue.

Of the 42 pregnancy-related events, there were 29 spontaneous abortions or miscarriages, with the remainder divided among 10 other pregnancy and neonatal conditions.

“When we looked at those outcomes and we compared the reporting rates, based on known background rates of these conditions, we did not see anything unexpected or concerning with respect to pregnancy or neonatal-specific conditions,” Dr. Shimabukuro said about the VAERS data.

The CDC did not collect data on fertility. “We’ve done a lot of work with other vaccines,” said Dr. Shimabukuro. “And just from a biological basis, we don’t have any evidence that vaccination, just in general, causes fertility problems.”

Also, Dr. Shimabukuro noted that the COVID-19 vaccine made by Janssen/Johnson & Johnson did not receive emergency authorization from the FDA in time to be included in the current report, but is being tracked for future reports.

Vaccination could benefit infants

In addition to the new safety data, experts continue to remind clinicians and the public that vaccination during pregnancy could benefit offspring. The unborn babies of pregnant women who receive the COVID-19 vaccine could be protected from the virus for the first several months of their lives, said White House COVID-19 czar Anthony Fauci, MD, at a briefing on March 10.

“We’ve seen this with many other vaccines,” Dr. Fauci said. “That’s a very good way you can get protection for the mother during pregnancy and also a transfer of protection for the infant, which will last a few months following the birth.”

Dr. Fauci also noted that the same vaccine platform used in Johnson & Johnson’s COVID-19 vaccine was successfully used for Ebola in pregnant women in Africa.

Dr. Shimabukuro has reported no relevant financial relationships.
